How to increase your phone's battery life?

                      Keep the battery healthy by fully charging and then fully discharging it at least once every two to three weeks. Exceptions to the rule are Li-Ion batteries, which do not suffer from the memory effect. Do not leave the battery dormant for long periods of time.

                      Keep the Batteries Clean - It's a good idea to clean dirty battery contacts with a cotton swab and alcohol. This helps maintain a good connection between the battery and the portable device.

                      Always use a battery charger, which is by the same manufacturer as your phone, it gives it more life. It also helps if you overcharge your battery now and then.

                      Don't  leave your cell phone near any source of heat, a common place being the dashboard of your car, as extreme heat may affect the battery. The battery also operates better at room temperature,means nomal temparatur.
